I agree, ask you proshop to watch you bowl and pick a layout. Im a med - med low rev 15.5 mph righty. Punched mine up just about the same as the #1 drill option on Ebonites drill sheet, basically pin up, 45 degree layout. Even with the slower speed it gets down the lane nice, and plenty on the back end in oob. Works great as long as there are some dry boards; either clean back ends, dry outsides or a broken down shot. Im loving mine, hope you do too!
